Reaction Steps

2,4-dichloro-5-fluoropyrimidine (166 mg, 1 mmol), N5,N5-dimethyl-1H-pyrazole-3,5-diamine (Method 34, 150 mg, 1.2 mmol), and DIEA (0.35 ml, 2 mmol) in ethanol (3 ml) was heated at 55° C. overnight. Solvent was removed, and the residue was purified by silica gel chromatography (by ISCO Combiflash with a gradient of 0-5% methanol in methylene chloride with 1% NH4OH). 100 mg product was obtained as a white solid (40%). MS: 257 (M+1); NMR (DMSO-d6, 400 MHz, 80° C.) δ11.60 (br, 1H), 10.26 (br, 1H), 8.23 (s, 1H), 5.73 (s, 1H), 2.76 (s, 6H).
